Pull-up and Abdominal Exerciser

ABSTRACT

An exerciser includes a base having a first frame and a second frame which is pivotably connected to the first frame, and a slide device. The first and second frames are arranged to have an angle therebetween. The slide device has a damper and a roller is connected to the slide rod so as to move on the second frame. The users put the base on the floor to use the exerciser as a pull-up exerciser. The users can also overlap the first and second frames and put the first and second frames on the floor to use as an abdominal exerciser. The damper generates different resistance to obtain different exercising levels.

FIELD OF THE INVENTION

The present invention relates to an exerciser, and more particularly, to an exercise with pull-up and abdominal training features.

BACKGROUND OF THE INVENTION

Many conventional exercisers provide different function for training and/or exercising different parts of the users' muscles. One of the welcomed exercisers is the pull-up exerciser which trains the muscles on the back and the arms. The pull-up exerciser includes a bar which is located above the user's chest and the user holds the bar and pulls the body upward by the arms. By repeatedly pulling the body upward, the muscles of the back and the arms are exercised. However, the users have to visit gyms or parks, rather than at home, to use the pull-up exerciser and this is inconvenient for the users.

The other welcomed exerciser is the abdominal training exerciser which includes a roller with two grips on two ends thereof, and the user holes the two grips and rolls the roller along rails so that the body extends forward until the body is bent like a triangle, and then the user pulls the roller back. By repeatedly operating the roller, the abdominal muscles are exercised. However, the resistance of the roller cannot be adjusted.

The present invention intends to provide a pull-up and abdominal exerciser which improves the shortcomings of the conventional exercisers.

SUMMARY OF THE INVENTION

The present invention relates to an exerciser and comprises a base having a first frame and a second frame which has a pivotal end so as to be pivotably connected to the first frame. The first and second frames stand on a floor and an angle is defined between the first and second frames. The second frame has a free end located in opposite to the pivotal end. A first grip portion and a bar are located at the pivotal end. A slide device comprises a slide rod and a damper, wherein the slide rod has a second grip portion extending from two ends thereof and a roller is connected to the lower end of the slide rod. The slide rod is slidably movable along the second frame. When using as an abdominal exerciser, the first and second frames overlapped to each other and the second frame faces upward. The damper has the first end fixed to the free end of the second frame, and the second end of the damper trains a pulley on the pivotal end and is fixed to a fixing member on the slide rod. When using as an abdominal exerciser, the user holds the second grip portion on the slide rod and the user's knees contact against the bar on the pivotal end to move the slide rod. When using as a pull-up exerciser, the first and second frames stand on the floor with an angle defined between the first and second frames, and the two ends of the damper are fixed to the free end and the pivotal end respectively. The user holds the first grip portion and the user's knees contact against the slide rod to pull user's body upward while the slide rod slides.

The primary object of the present invention is to provide an exerciser which has two different exercising functions and the users can operate the exerciser as an abdominal exerciser or a pull-up exerciser.

The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 5, the exerciser of the present invention comprises a base 1 having a first frame 11 and a second frame 12 which has a pivotal end 10 pivotably connected to the first frame 11. The first and second frames 11, 12 can be overlapped to each other and put on the floor, or to stand on the floor by an angle defined between the first and second frames 11, 12. The first frame 11 is a retractable frame and an adjustment member 13 is connected to the pivotal position between the first and second frames 11, 12 so as to adjust the angle between the first and second frames 11, 12. The adjustment member 13 comprises a semi-circular disk 131 with multiple holes and a pin 133 extends through one of the holes to fix the angle between the first and second frames 11, 12. The second frame 12 has a free end 120 located in opposite to the pivotal end 10. A first grip portion 101 and a bar 102 are located at the pivotal end 10. A slide device 2 includes a slide rod 21 and a damper 23. The slide rod 21 has a second grip portion 201 extending from two ends thereof. A roller 211 is connected to the lower end of the slide rod 21 so that the slide rod 21 is slidably movable along the second frame 12. The slide device 2 comprises an installation rod 25 which is parallel to the slide rod 21 and a first distance 251 is defined between the installation rod 25 and the slide rod 21. The first distance 251 accommodates the user's knees when the user uses the exerciser as a pull-up exerciser. The installation rod 25 can be disengaged from the second frame 12 and is connected to the pivotal end 10 and parallel to the bar 102. A second distance 252 is defined between the installation rod 25 on the pivotal end 10 and the bar 102. The second distance 252 accommodates the user's knees when the user uses the exerciser as an abdominal exerciser.

When using as an abdominal exerciser, the first and second frames 11, 12 are overlapped to each other and the second frame 12 faces upward. The damper 23 has a first end fixed to the free end 120 of the second frame 12, and a second end of the damper 23 trains through a pulley 127 on the pivotal end 10 and is fixed to a fixing member 212 on the slide rod 21. The user holds the second grip portion 210 on the slide rod 21 and the user's knees contact against the bar 102 on the pivotal end 10 to move the slide rod 21 by using the arms and the waist. The slide rod 21 has the damper 23 so that the user has to overcome the resistance from the damper 23 to move the slide rod 21. When releasing the second grip portion 210, the damper 23 pulls the slide rod 21 back to its original position. By repeatedly operating, the muscles of the abdominal portion are exercised.

When using as a pull-up exerciser, the first and second frames 11, 12 stand on the floor with an angle defined between the first and second frames 11, 12. The two ends of the damper 23 are fixed to the free end 120 and the pivotal end 10 respectively. The user holds the first grip portion 101 and the user's knees contact against the slide rod 21 to pull user's body upward while the slide rod 21 slides by the user's knees. By repeatedly operating, the muscles of the arms and the back are exercised.

The bar 102, the slide rod 21 and the installation rod 25 are wrapped with soft material so as to protect the user's knees when the knees are accommodated in the first or second distances 251, 252.

The exerciser can switch the two different functions as mentioned above and the exerciser can be used at home. By using the damper 23, different levels of exercising are obtained.

While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
